Grade = how their written analysis reads (A best). Trader score = how their last-20 timestamped calls performed vs SPY. · Analyst brief as of 2026-06-22.
Across their last 20 scored bets: 45% hit rate, -0.10% mean alpha, trader score -0.41. Their last-14d mentions, direction-adjusted, have moved -5.0% since posting (mean over 131 mentions with price data).
Jaymin_Alpha is overwhelmingly mapping Korean AI infrastructure beneficiaries, with the densest work in HBM/memory equipment, optical/network bottlenecks, power/grid infrastructure, and value-up re-rating. The distinctive read is a rotation from obvious AI leaders into second-order Korean suppliers tied to SK Hynix/Samsung capex, Nvidia Rubin, AI-RAN, and grid constraints. Late-week posts broadened from memory and optical into telecom, energy highways, space/solar, and bank/value-up baskets, with no explicit position flip or disclosed trade.
The author is consistently bullish and heavily concentrated in Korean AI supply-chain mapping, especially memory/HBM equipment, optical/network bottlenecks, AI-RAN, and grid infrastructure. There are no CALL_DIRECTIONAL trades or position disclosures, so adds, trims, exits, and flips are not evidenced in the supplied signals. The late-week direction is broader rather than bearish: repeated memory-capex baskets plus new AI-RAN, power/grid, and space/solar baskets create theme-level pump-risk across many small supplier names, though no single ticker exceeds half of a major theme.

Grade is our human read-worthiness rating; trader score is a rolling 20-bet hit-rate/alpha composite — different things, often disagreeing. “Since then” is direction-unaware in the table; the summary line above adjusts for which way they leaned.
